- In order to produce thesesections of circular boxes I employ certain mechanical elements necessary; for the assembling of the parts of the. sections, as will be seen by reference to thefaccompanying ldrawings, in

7 which I have showna complete, embodiment of the present invention.

In carrying `outtlie4 invention I employ anysuitable framework for supporting the moving vparts and retaining in position the .stationary parts., v Y, y. c

Referring to the drawingsby numeralsfl` indicates asuitable stationary vertically arranged standard surrounded by a rotatably mounted sleeve 2, to which is fixed a second j'. sleeve.' as 3, provided with ,laterally'extend- "'ing arms v4:, 4,v carrying brushes 5, 5, best preferably beveled gearwhe'el as 6, surrounds sleeve 2, beneathy seen in Figs. 9 and 10.

sleeve, 3, andspaeed beneath the wheel 6, is `a similar-,wheel 7. .Between the wheels 6 and 7 and surrounding `the sleeve 2, is a col-l lar 8,'previded with a suitable laterally extendinglug 9`forming a bearing for the journalof'a 'shaft 10, said shaft being provii'ledfwith,abeveled gear 11, meshing with "bth ofig'ea'r wheels and T. The outer end of shaft` 10 is preferably journaled in any '50 suitable support-andcarries a sprocket wheel as 13 between said support and gear 11.' The sprocket wheel 13 is designed to receive motion through a suitable chain 14 passed about a sprocket 15 carried by the i main operating shaft 16. Carried by the Fig. 30 represents an enlarged detail side elevationl 5 ofthe tape applying wheel yand rubber. Fig.

of the tape carrying wheel shaft. F ig.r33l

wheel 6 is a circular'plate 17, the gear wheel 7 being fixed to sleeve 2 so that rotation of gear 11 will swing the brushes 5 about in one direction and rotate the plate 17in ,they

other.

Secured near the upper end of standard 1 is a suitable spider 18carrying an annular brush inclesing housing 19, said housingbeing provided with radially extending brackets 20, supporting an outer ring 21,

which ring is preferably of ythe ,sainediam-i eter as the plate 17. The ring 21 isI prefei'- ably broken at one point and one end is bent inwardly as at 22, and the other outwardly as at 23, leaving a space therebetween apr proximately the same as that between heusing 19 and the said ring 21.- Suitable tan-` gentially arranged arms as 24,24, are secured to the lower edge of the housing 19 and are preferably beveled as at 25, in the direction of movement of the plate 17.

' Each of the sections to be formed by the present improved mechanism, is as above suggested, made up`= of a "ring, as 26, a disk 27, and nieansfer securing t-he parts togetherv will be best seen by reference to Fig. 33.

The housing 19 is designed to receive a supply of rings 26, said housing having its lower edge spaced above plate 17a distance' equivalent to the width of one of said rings, and said; housingalso being spaced Afrom the ring 21 a distance" equal tothe diameter of i ring 26, said ring 21A-having its lower edge contiguous .plate 17. An approximately semi-circular plate as 2SA is preferably securedto the lower edge of the housing 19 with one-end near end 22 of ring 21 and the said plate extending from'this point in an opposite directionto the direction of nieve- 'nient of the plate 17, whereby' the rings 26 within housing 19 may be discharged there- Y from beneath the edge thereof -for approxi-` mately one half the circumference of the said housing, the said housing remaining stationary while the contiguousparts are moving, whereby said rings 26 are caused to be fed out of the space between ends 22 and `23 ofring 21.. In order to control the yfeed of said rings and time their discharge, `a

suitable-feed wheel asv 29 is interposed in thepath of movement of said rings. The wheel `29 is formed with a plurality of radial arms 30 having their-edges curved for receiving a ring 26 between-each two of the. same, each arm 30' being :of a length to extend from ,ringl 21 tohousing 19, whereby the rings 26 may only be fed out between theeiids 22 and 23.of ring 21,1 in-timedrelation to the movementofwheel 29. 1,- i

In order to rotatethe wheel 29 timed to the operation of other parts Tof the-present mechanism as best seen in Figs. 11 12 and f 13 lof the drawings I preferably secure the same to a if'ertical shaft 31, providedwitlr a ratchet 4wheel 32 designed to be engaged by a suitable pawl 33, spring pressed and mechanism a reciprocating movement is imparted to pitman and the block 34 is rocked back and forth, each forward movement throwing forward the shaft 31 a dis tance sutlicient to rotate wheel 29 the necessary distance to discharge one of the rings 26. As the rings 26 are discharged by the rotation of wheel 29, they fall into Contact with a roller 42, ournaled beneath the horizontal plane of plate 17, and having one of its journalsprovided with a power pulley 43, receiving power from shaft 16 through any suitable belt or cable mechanism designed to rotate a pulley 44, mounted upon a shaft carrying a beveled gear 45, meshing with a similar gear 46, which latter gear carries a pulley 47 about which 1s passed abelt or cable 48, said cable being also passed about the pulley 43. By ,this chain of `mechanism rotary motion of shaft 16 from one plane is transferred to a plane at right angles. The roller 42 may have a smooth surface, as seen in Figs. 2 and 9, or may be provided with corrugations or otherwise suitably' roughened, as seenin Figs. 6 and 14, for increasing its gripping capacity. A chute as 49 particularly disclosed in F ig. 14 leads downwardly on that side of roller 42 nearest the periphery of plate 17, whereby the ring 16 striking said roller 42 will be directed down said chute 49. At the lowex` end of chute 49, the housing forming said chute is transversely apertured, as at 5G said aperture preferal'ily being of the size and shape for snugly receiving and permil:` ting the passage laterally of one of the rings 26. I A plurality of longitudinally slidable radial arms 51, 51 best seen in Figs. 14 and 15,

extend into the aperture 50, and have their contacting ends beveled rearwardly, .as at- 52. The outerends ofA the arms- 51v are f shouldered,- at53, and provided with stems 54, extending throughl inclosing housings 55, a spring as 56 encircling each stem 54 and having one end pressing'against the outer end of the housing 55 and the other f end against the shoulder 53,'whereby said arms are normally held with Ytheir inner ends in contact with each other centrally of the aperture 52.' Each of the arms 51`is preferably formedfwith a laterally projecting lug 57 designed to move in a slot 53 in its respective housing for guiding the said arm. Mounted in suitable supports 59 is a slidably arranged shaft as 60 seen in Figs. 15, 16, and 17, extending in the hori` Zontal plane of aperture 50 and carrying on its inner `end a plunger v61, tapered to conical form as at 62, and provided with an annular shoulder 63 broken by longitudinal grooves 64, 64, equal in number to the number of arms 51 and extending in the same planes therewith. Pivotally connected with shaft 60 intermediate its mountings is an operating lever 65, vpivoted as at 66, intermediate its length and having its free end engaging a cam G7 carried by the main shaft 16, the said cam being of a shape for swinging said lever in such manner as to throw forwardly the plunger 61 relative to the -movement of the other parts. of the mechanism. The support 68 for the housing of the chute 49 is provided with a cylindrical bore 69, registering with aperture 50, and extending to the opposite side of said support to that upon which the said housing is secured.

The movement of lever 65 effected by cam G7 is timed tothe operation of wheel 29 so that each time a ring 26 is lodged within aperture 50, the plunger 61will move forwardly, the cone 62 will spread the arms 51,

causing the ring to lie flush with the shoul-V der G3, and the said arms to jump said ring` and extend 'into the grooves 64. The can: 67 next causes the plunger 61 to retrace its movement whereby the. said ring will be left within bore 69 by reason of the fact that the rear portion of the ends of arms 51 will e engage the same and prevent its return with the plunger. The bore 69 may be of any length desired according to the width of the support 68 and in operation is preferably kept filled with the rings 26.

Rising vertically from the opposite side of support 68 to chute 49 are suitable standards 70, 70, as particularly disclosed in Figs. 3 and 5 of the drawings formed with longitudinal grooves 71, 71, designed to form ways for a slide 72, arranged to move therebetween longitiidinally of the said standard. Secured to the rear of standard 7 0 is a back plate 73, slotted longitudinally, as at 74,-for permitting the passage of a pin or bolt 75 carried by a block 7 6, slidable longitudinally within a yoke 77, formed upon the end of an operating lever 78, said leverbeing pivoted intermediate its length, as'at 79, and pivotally connected, as at 80, to a suitable strapy 81, engaging a cam 82, carried by the main 83, 83, tothe front face 'of slide 72, as seen :A in Figs. 5 and 28 is a face plate 84, of greater width than the width of the slide so as to extend beyond the inner edges of the standard70 and adapted to move in contact therewith with the movementof the slide. The

lower end of the slide 72 is formed with an annular ball race 85, adapted to receive suitable anti-friction balls or rollers 86 against the outer edge of which is held a disk 87 vretained rotatably in position by means of a screw 88, passed through said disk and g tical plane of plate 88 vequal to the thick' into slide 72. The outer face of disk 87 carries a circular plate 88', secured to said disk by means of screws 89, as seen in Figs. 5, 28 and 28. The d isk 87 and disk 27 of the box are rotated during the operation of applying the tape-,the 'clampingl action of fingers 90 described belowy not being sufficient to prevent this rotation. The plate 84 is of course formedwith an annular aperture -for permitting the arrangement of disk 87, said plate extending a distance outside the veri ness of Aone of disks `27, said disk 87 and plate 88 beingof the saine diameter. Pivoted to, plate 84 upon each side thereof is a finger 90,- each being pressed by a suitable spring 91, and guided by slots 92, engaged by pins 93, passed into plate 84. The inner.

edges of lingers 90 are struck on an arc of Va circle and are designed normally to regis'- .ter with the circular aperture in plate 84.

Referring to Fig. 23 it will be observed that the finger 90 shown at the left is proyvidedwith an offset portion for the accommodation of the disk, and for carrying' the 'tape to. the rear of the disk when su'cli tape inder 94 is a seini-circular trough 95, slotted on each side longitudinally, as at 96, 9G, and .designed to contain a supply of disks-27, a plungerv 97, normally pressing the saidsupply of disks into said cylinder 94. The

.plunger 97 is provided with laterally extendinglugs 98, vmoving in slots 96,- each being engaged by a ring99, carried by a suitable cable 100, passed about any suitable r pulley 101 secured onto the sidel of cylinder 94 vand forwardly and about a similar pulley 102 carried by the front end of trough 95, the said front end of the trough being supported in position by a suitable standard 103, of the main framework.'- The said 'cables have their forward ends passed downwardly and secured together by link 104, to which link is attached a comparatively heavy weight 105, whereby, as above suggested the plunger 97 is caused to normally press the supply of disks 27 toward the cylvinder 94, but at certain times during the operation of the present improved mechanism, as 'will hereinafter appear it becomes necessary that the pressure upon said disks be released. lVitli this object in' view the front end of trough 95 is provided with a cylindrical portion 106 closed at its front end by a suitable head 107, centrally through which is passed a shaft 108 having its rear end attached to the front end of the plunger 97, said shaft being provided with a plurality of longitudinal grooves 109. A plurality Iof angular fingers 110, seen best in Figs. 20 and 22 ai'e carried by the head 107 and secured thereto by transverse straps 111, the horizontal portions of said fingers 110 lying within the grooves 109.

Spaced below shaft 108 and supported in standard 103, at its front end and by stand-A ard 112 near its rear end is a shaft 113, the front end of said shaft carrying a` sleeve 114 formed at its front end with an annular groove 115, ldesignedto be engaged by the arms of the bifurcated end of the lever 116, pivoted, as at 117, and engaging acam '118, at its free end, said cam being carried by the .ma-in power shaft` 16. The contour of the groove in cam 118 is such as to swing the bifurcated end of lever 11G forwardly in timed relation to the movement of slide 72. A sleeve 119, slidably surrounds shaft 108, outside the head 107 and is connected by a web 120 with sleeve 114. The sleeve 119 is provided with a plurality of pivotally mounted cams 121, pressed by springs 122,

-at their outer ends in an opposite direction to that of themovement of plunger 97, the inner ends of said cams engaging the grooves 109, and being held in contact therewith by said spring. The inner ends of cams 121 are of approximately circular form, said cams being pivoted off center, whereby movement of sleeve`119 in the direction of movement of plunger 97 will cause the said inner ends of the cams 121 to rotate in an opposite direction lto the pull of springs 122, whereby the shaft 108 will be released and the plunger 97 affected by .weight 105. It will be observed that as r0- cam will cause their positive clamping of plunger 108. In the operation of the Adevice, the bifurcated end of lever ll'is swung forwardly at the appropriate time to effect such clamping of the canisv'12,1whereby 'the shaft 108 isinoved longitudinally forwardly sufficiently to release the pressure of plunger 97 upon the supply of disks 27 in trough 95.

The standard 112 forming the rear supiis 126, covering one quarter of a circle, .where-` by the four sections when brought together form a circular head, each of said plates being formed in front nf its portion 126 with a bevel 127 leading upwardly to a circular portion 128, extending to Lthe shoulder formed by portion 126. The bevel 127 extends downwardly to the forwardly extending arm 129 designed to carry a eomparatively .strong spring 130, which spring in operation has its free end secured to the rear end of shaft 113, said spring being sol formed as to exert an outward pressure upon its respective plate 125. As before mentioned the shaft 113 is surrounded by sleeve 124 which is slidable thereon, and the rear end of which surrounds the arms 129 of the expanding former. The said rear end of sleeve 124 is provided with an annular shoulder 131, of a width equal to that of the shoulder formed by the portions 126, the

inner edge of said shoulder 131, being beveled, as at 132, for purposes hereinafter inentioned. Sleeve 124 is of a diameter equal to that of the inner surface of ring The sleeve 124 is grooved longitudinally, as at 133, for receiving a key 134 carried by a collar 135, which collar is formed with a toothed flange 136 extending outside the housing 123. A lug 137 is carried by housing-123 and extends into an annular groove 138 formed in sleeve 124 whereby the saine is free to rotate, but is held against longitudinal movement'. A suitable bracket 139 extends vertically upward from the main frame, is bored transversely, and carries a rock shaft 140, to one end of whichv is se ein-ed an arni 141, and to the other end a crank 142. To the free end of the crank 142 is pivotally attached a pitiiian 143extendingto the inain shaft 16 and provided with a yoke 144 surrounding the same and a traveler 145, engaging a cam 146 carried by said shaft 16, said eain throwing forward the piiinaii 143 and any suitable means as a spring 147 being` employed for retraeting said pitnian soon as permitted by said nain 146. The upper end of arm 141 is provided with a segmental rack 148, meshing;` with the teeth upon the [lange 136, whereby the sleeve1124'willibe osrillated by the moveiin-nt of'pitman 143..` Shaft 113 is provided.. with a longitudinal groove 149 engaged by' "J5 a ley extending inwardly iroin pinion 150, i

1,ooe,885 V gear wheel 151, rotatably mounted upon a shaft 152. Secured to the gear wheel 151 and surrounding shaft 152, seen in Figs. 7 and 25 is an annular housing 153, said housing inclosing disks 154 and 155 spaced apart and carrying cams 156 therebetween which cams are pivoted, as at 157, to the inner plate and provided with arms 158, slotted as at 159, for inclosing pins 160 carried by the outer plate 155.

The circular face of each of the cams 156 lies in Contact with the inner surface of through plate 155, whereby rotation of said plate in one direction will cause the arms 158 of said cams-to swing in such .manner as to cause, the circular edges of said cams to 153, so as to cause said housing and gear wheel 151 to rotate with thefdisk 155. It' will be observed that a reverse rotation of disk 153 will swing arms 158 in a direction for releasing the engagement of cams 156.- Extending inwardly from disk 155 is a pin 161 and extending outwardly from disk 154 is a similar pin 162, the free ends of said plane. The said ends of ins 161 and 162 are connected by a prefera ly coiled spring 163, whereby upon release of housing 153 by cams 156, the disk 154 will be moved to its initial position, said disk being freely rotatable within housing 153. The disk 155 is preferably formed integral with a laterally extending sleeve 164 to which is pivoted, as at 165, ,a pitman 166, pivotally connected at its opposite end to a yoke 167 extending upon either side of the main power shaft 16, said pitman being provided with a traveler 168 riding upon a cam 169 carried by said shaft 16. A suitable spring as 170 is connected with pitman 166 and sesame after each forward stroke through the operation of cam 169. A

The shaft 152 is preferably j oiirnaled at each end in a suitable bearing box 171 as seen in Figs. 2,31 and 32,slidably mounted within a suitable way 172, and pressed from beneath by a spring 173. Each of said boxes is limited in its movement by set screw 174, and each ofsprings 173 has its tension controlled by a similar screw 175. It will be apparent that shaft Y152 by reason of its particular mounting is capable of movement in a vertical plane. a suitable level' as 176 engaging said shaft near each end thereof,

criiin intermediate its length and at the openeireling shaft 16, said collar carrying a traveler 177 engaging a cam 177, said cams l being carried by shaft 16.

y Fixed to shaft 152 is a tape feed Wheel housing 153, and the pins 160 extend each of said levers being pivoted to a ful' said pinion, in operation meshing with a l tightly grip the inner surface of the housing' Y pins lying in the sametransverse vertical 1 cured to a xed point for retracting the l posite end being pivoted to a collar 176
